Natural Diamond Wire Drawing Dies
Coolervie supplies precision natural diamond wire drawing dies (ND dies) for fine and ultra-fine wire production. Made with carefully selected natural diamond, these dies provide a smooth working surface and low friction, helping manufacturers achieve consistent wire surface quality and accurate diameter control in demanding drawing applications.
Natural diamond dies are suitable for fine copper wire, magnet wire, precious metal wire, and selected specialty wire applications. Each die can be specified according to the wire material, target diameter, required tolerance, and drawing conditions to meet your production needs.
PRODUCT SPECIFICATIONS
Hole Sizes
0.02mm to 1.20mm
Die Material: Carefully selected natural diamond.
Applications
Coolervie natural diamond wire drawing dies are designed for fine and ultra-fine wire production where surface finish and dimensional consistency are critical. Their smooth working surfaces make them suitable for applications involving fine copper wire, magnet wire, gold and silver wire, and selected specialty wire products.
The right die specification depends on the wire material, incoming and finished diameters, reduction schedule, lubrication, and required surface quality. Providing these details helps our team identify a suitable natural diamond die for your drawing process.
Typical Markets
Natural diamond wire drawing dies serve specialized industries where fine wire dimensions and surface quality are important.
High-End Electronics: Fine copper wire and selected bonding-wire applications that require consistent diameter control and a smooth surface finish.
Medical Devices: Precision wire components for applications requiring controlled dimensions and a high-quality surface, subject to the specific material and regulatory requirements.
Precious Metals: Fine gold, silver, and platinum wire drawing for applications where surface appearance and dimensional consistency matter.
ADVANTAGES
Excellent Surface Finish for Fine Wire
Natural diamond can be polished to an exceptionally smooth working surface, making it well suited to fine wire drawing applications with demanding surface-finish requirements. Proper die geometry and process control help maintain consistent wire surface quality.
Designed for Fine and Ultra-Fine Wire Drawing
Natural diamond wire drawing dies are suitable for fine and ultra-fine wire production where accurate bore geometry and consistent finished diameters are essential. The appropriate die design should be matched to the wire material, target diameter, and drawing process.
Smooth Working Surface and Reduced Drawing Friction
The smooth surface of a natural diamond die can help reduce friction during wire drawing when the die profile, lubricant, and operating conditions are properly matched. Appropriate process settings help support stable drawing performance and wire surface quality.
High Thermal Conductivity
Natural diamond has high thermal conductivity, helping transfer heat away from the working area. Combined with suitable lubrication and drawing parameters, this property supports thermal management during precision wire drawing operations.
Consistent Performance in Suitable Wire Drawing Applications
For suitable soft-metal and precious-metal drawing applications, natural diamond dies can help maintain a consistent working surface and finished wire quality over production runs. Actual die life depends on the wire material, drawing conditions, lubrication, die geometry, and maintenance practices.
